CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit, under 35 U.S.C. §119(e), ofU.S. Provisional Application No. 61/422,874 which was filed Dec. 14,2010 and which is hereby incorporated by reference herein.

BACKGROUND

The present disclosure relates to patient support apparatuses for useduring surgery. More particularly, the present disclosure relates topatient support apparatuses operable to reposition a patient duringsurgery.

In some surgeries, it may be advantageous for the patient to bepositioned in a lateral position so that a surgeon can access a firstsurgical sight and then repositioned so that a surgeon can access othernecessary surgical sights. This dual approach surgery can require thepatient to first be positioned in a lateral position, lying on his side,on a first patient support. The patient may then be transferred to astretcher while the first patient support is replaced with a secondpatient support configured to support the patient in a differentposition. Next, the patient is transferred onto the second patientsupport so that the next surgical approach can be performed. Otherpatient supports allow the patient to be supported in a lateral positionand then repositioned relative to the same patient support so that thepatient is positioned in another position. Repositioning a patientduring surgery on different patient supports or even on the same patientsupport can be dangerous for the patient and/or difficult for caregivers.

DETAILED DESCRIPTION

Referring to FIGS. 1-20, an illustrative surgical support 10 forsupporting a patient in a number of position during surgery is shown. Asshown in FIG. 1, the surgical support 10 includes a foundation frame 12and a patient support 14 mounted on the foundation frame 12. Thefoundation frame 12 is illustratively a “Jackson Table” as is known inthe art but in other embodiments may be another suitable frame forsupporting the patient support 14. The patient support 14 is coupled tothe foundation frame 12 for pivotable movement about a patient supportaxis 14A parallel to the length of the patient support 14 so that apatient resting on the surgical support 10 can be repositioned during asurgical procedure.

By pivoting the patient support 14 about the axis 14A, the patientresting on the patient support 14 can be moved between a lateral (orside-lying) position, as shown for example in FIG. 36, and a prone (orface-down) position, as shown for example in FIG. 39. Alternatively, thepatient supported on the patient support 14 can be moved between alateral position, as shown in FIG. 48, and a supine (or face-up)position, as shown in FIG. 53. Moving a patient between the lateralposition and the prone/supine position during a surgical procedure maybe undertaken in a number of medical procedures to increaseaccessibility of different parts of the patient's anatomy duringdifferent parts of a procedure. For example, during an extreme (ordirect) lateral interbody fusion (XLIF/DLIF), a surgeon may access thepatient's spine while the patient is in the lateral position to place aspinal implant and then move the patient to the prone position to placescrews, plates, rods, and the like to secure the implant.

The patient support 14 illustratively includes a base beam 16, a legsupport 18 that is pivotably coupled to the base beam 16, and a guide 20for guiding the leg support 18 when the leg support pivots relative tothe base beam 16. The base beam 16 includes a first section 22configured to support the torso of the patient supported on the patientsupport 14. The leg support 18 is configured to support the legs of thepatient supported on the patient support 14. The leg support 18 pivotsabout an axis 18A between a horizontal position parallel to the firstsection 22 of the base beam 16, as shown in FIG. 6, and a number ofdeclined positions forming an angle α with the first section 22 of thebase beam 16, as shown in FIG. 8. The leg support 18 may also be pivotedup from the horizontal position to a number of inclined positionsforming an angle θ with the first section 22 of the base beam 16, asshown in FIG. 8. In the illustrative embodiment, α is about 25 degreesand β is about 5 degrees.

The leg support 18 may be moved to an inclined position to compensatefor the width of the patients hips and to straighten a patient's spine.As shown in FIG. 37, moving the leg support 18 from the inclinedposition or the horizontal position to one of the declined positionswhile a patient is supported on the patient support 14 causes lateralflexion of the patient's torso relative to the patient's legs. When thepatient is subjected to lateral flexion, the patient's pelvis is movedaway from the patient's rib cage along the side of the patient spacedapart from the base beam 16 and the leg support 18. Space between thepatient's pelvis and rib cage may allow a surgeon to access portions ofthe patient's anatomy such as the spine (especially the lower vertebrae)and kidneys, through the patient's side. In one example, a surgeon mayaccess the patient's spine from the side during an XLIF/DLIF procedurewhen the surgeon is placing a spinal implant.

In the illustrative embodiment, as shown in FIG. 1, the base beam 16 ofthe patient support 14 has a rectangular cross-section and includes thefirst section 22, a second section 24, and a jog 26 extending from thefirst section 22 to the second section 24.

In some embodiments, the patient support 214 may be used with a surgicaldrape 160 shown in FIGS. 17A-17C. The surgical drape 160 includes a basesheet 162, a first tear-away sheet 164, and a second tear-away sheet 166as shown in FIG. 17C. The base sheet 162 is formed to include an opening168 as shown, for example, in FIG. 17C. The first tear-away sheet 164extends from a top edge 170 of the base sheet and is folded over thebase sheet 162 to cover the top half of the opening 168. The firsttear-away sheet 164 is secured in position over the top half of theopening 168 by strips of adhesive 172, 174 applied on either side of theopening 168. The second tear-away sheet 166 extends from a bottom edge176 of the base sheet and is folded over the base sheet 162 to cover thebottom half of the opening 168. The second tear-away sheet 166 issecured in position over the bottom half of the opening 168 by strips ofadhesive 178, 180 applied on either side of the opening 168. In otherembodiments, the opening may be a pair of openings corresponding to thetop half and the bottom half of the opening 168 in the base sheet 162.In some embodiments, light stitching or other break-away means may beused instead of adhesive.

A method of use of the surgical drape 160 may include the steps of (i)wrapping the drape around a patient, (ii) breaking the bond of the firsttear-away sheet 164, (iii) pulling the first tear-away sheet 164 awayfrom the base sheet 162 to expose the top half of the opening 168thereby accessing a first surgical site, (iv) breaking the bond of thesecond tear-away sheet 166, and (v) pulling the second tear-away sheet166 away from the base sheet 162 to expose the bottom half of theopening 168 thereby accessing a second surgical site. Specifically, inthe illustrative embodiment, the surgical drape 160 is wrapped aroundthe patient so that the top half of the opening 168 is positioned over apatient's side abdomen and the bottom half of the opening is positionedover the patient's back. Steps (ii) and (iii) may be performed while thepatient is supported in a lateral position on the patient support 14 andsubjected to lateral flexion as shown in FIG. 17B. Steps (iv) and (v)may be performed after a caregiver rotates the patient support 14 aboutthe axis 14A relative to the foundation frame 12 so that the patient issupported in the prone position as shown in FIG. 17C. Thus, during atwo-site surgery such as an XLIF/DLIF only a single surgical drape maybe used. Other methods of using the surgical drape 160 with the surgicalsupport 10 may be used where accessing two different surgical siteswhile the patient is in two different positions is desirable.

Another illustrative surgical support 210 is shown in FIGS. 21 a-27 b.The surgical support 210 includes a foundation frame 12 and a patientsupport 14 mounted on the foundation frame 12. The foundation frame 12is illustratively a “Jackson Table” as described with regard to thesurgical support 10 described above and similar reference numbersindicate similar components. The patient support 214 is coupled to thefoundation frame 12 for pivotable movement about an axis 214A parallelto the length of the patient support 214 so that a patient supported onthe surgical support 10 can be repositioned during a surgical procedure

By pivoting the patient support 214 about the axis 214A, the patientsupported on the patient support 214 can be moved between a lateral (orside-lying) position, as shown for example in FIG. 21 b, and a prone (orface-down) position, shown in FIG. 26 b. Alternatively, the patientsupported on the patient support 14 can be moved between a lateralposition and a supine (or face-up) position. Moving a patient betweenthe lateral position and the prone/supine position during a surgicalprocedure may be undertaken in a number of medical procedures toincrease accessibility of different parts of the patient's anatomyduring different parts of a procedure. For example, during an extreme(or direct) lateral interbody fusion (XLIF/DLIF), a surgeon may accessthe patient's spine while the patient is in the lateral position toplace a spinal implant and then move the patient to the prone positionto place screws, plates, rods, and the like to secure the implant.

The patient support 214 illustratively includes a base beam 216, a legsupport 218, and a torso support 220 as shown 21 a. The base beam 216includes a first section 222 underlying the torso support 220 and asecond section 224 underlying the leg support 218. The leg support 218is configured to support the patient's legs and is pivotably coupled toan end 228 of the base beam 216. The leg support 218 is movable betweena horizontal position that is substantially parallel to the base beam216 (shown in FIG. 21 a) and a number of inclined positions forming anangle α with the base beam 216. The torso support 220 is configured tosupport the patient's torso and is pivotably coupled to an end 230,opposite the end 228, of the base beam 216 (shown in FIG. 24). The torsosupport 220 is movable between a horizontal position that issubstantially parallel to the base beam 216 (shown in FIG. 21 a) and anumber of inclined positions forming an angle θ with the base beam 216(shown in FIG. 24). The base beam 216, leg support 218, and torsosupport 220 are made from radiolucent materials. In other embodiments,the base beam 216, leg support 218, and torso support 220 arenon-radiolucent.

As shown in FIG. 23 b, inclining the leg support 218 and the torsosupport 220 relative to the base beam 216 causes the leg support 218 andthe torso support 220 to be spaced apart from the base beam near themiddle of the patient support 214. Thus, a patient supported on thepatient support 214 is moved into lateral flexion wherein the patient'storso is angled relative to the patient's legs. When the patient issubjected to lateral flexion, the patient's pelvis is moved away fromthe patient's rib cage along the side of the patient spaced apart fromthe base beam 216 and the leg support 218. Space between the patient'spelvis and rib cage may allow a surgeon to access portions of thepatient's anatomy such as the spine (especially the lower vertebrae) andkidneys, through the patient's side. In one example, a surgeon mayaccess the patient's spine from the side during an XLIF/DLIF procedurewhen the surgeon is placing a spinal implant.

The base beam 216 illustratively has a C-shaped cross-section andincludes the first section 222, the second section 224, and a step block226 as shown, for example, in FIG. 24. The first section 222 forms thefirst end 228 of the base beam 216. The second section 224 forms thesecond end 230 is stepped down from the first section 222 and issubstantially parallel to the first section 222. The step block 226 iscoupled between the first section 222 and the second section 224 so thatthe first section 222 is stepped down from the second section 224. Inother embodiments, the base beam 216 may have another shapecross-section and may be formed from a single component.

The patient support also includes a first adapter 221 and a secondadapter 223 for mounting the patient support 214 to the foundation frame12 as shown in FIG. 25. The first adapter 221 is coupled to the firstend 228 of the base beam 216 and includes a pair of side panels 225 anda yoke 227. The second adapter 223 is coupled to the second end 230 ofthe base beam 216 and includes a pair of side panels 229 and a yoke 231.The yokes 227, 231 are configured to releasably engage the adapter holes72 of the foundation frame 12.

The frame 245 extends out from the mount243. The proximal brace 247 is coupled to the frame 245 near the mount243 and forms an arcuate L-shape to support a patient on the patientsupport 214 in the lateral, prone, or supine position. The distal brace249 is coupled to the frame 245 and is spaced apart from the proximalbrace 247 to form a relief opening 251 between the proximal brace 247and the distal brace 249. The distal brace 249 is ramped and isconfigured to support a patient on the patient support 214 in the proneor supine position. In the illustrative embodiment, the relief opening215 is augmented by a U-shaped surface 253 formed by the frame 245between the proximal brace 247 and the distal brace 249.

The proximal and distal braces 247, 249 are shaped to encourage apatient toward the relief opening 251 between the proximal and distalbraces 247, 249 when the patient is supported in the prone or supineposition. The relief opening 251 is sized to relieve the patient's groinwhen the patient's hips are supported in the prone position on the torsosupport member 242. Additionally, the relief opening 251 is sized toallow surgical lines, such as catheters, to run along the length of thetorso support members 242. In some embodiments, the torso supportmembers 242 may include straps for securing a patient to the torsosupport 220. Additionally, a head support, an arm support, and a legsupport wrap as described above with regard to the patient support 14may be used with the patient support 214.

The patient support 214 also includes a drive (not shown) configured tosimultaneously move the leg support 218 and the torso support 220between the horizontal positions and the inclined positions. In otherembodiments, the leg support 218 and the torso support 220 may beindependently moved by the drive for all or a portion of their movementfrom the horizontal positions to a maximum inclined position. In someembodiments, the drive may be a manual drive with a hand crank. In otherembodiments, the drive may include a motor and a controller.
